CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 258,320, dated May 23,1882.

Application filed February 9, 1882. (No model.)

To all whom it may concern:

Be it known that I, HOMER A. SAMPSELL, a citizen of the UnitedStates ofAmerica, re siding at Salem, in the county of Oolnmbiana and State ofOhio, have invented certain new and useful Improvements in AutomaticRailroad-Oar Couplings 5 and I do hereby declare the following to be afull, clear, and exactdescription of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings; and to theletters or figures of reference marked thereon, which form a part ofthis specification, and in which- Figure 1 is a longitudinal verticalsection showing the tumbling-latch holding the pin up ready to receivethe link. Fig. 2 is a longitudinal vertical section showing thetumblinglatch pushed back by the entering link and the pin down. Fig. 3is a cross-section taken on the line of the pin. Fig. etis anisometrical projection of the tumbling-latch.

A represents a draw-head for railroad-cars, provided with a cavity, B,of suitable size and form, for the reception of a tumbling latch, O, ofpeculiar construction. The cavity extends forward to the pin-hole D andcommunicates with the back end of the mouth E of the drawhead, so as toadmit the link M. The lower side of the cavity is open, so as to permitof the insertion and withdrawal of the tumblinglatch. The tumbling-latchO is hung upon a pin, G, which passes through. the sides of thedraw-head and through an oblong slot, H,

set at an angle of about forty-five degrees and near the end of thelatch. The front end'of the latch terminates in a toe or projection, I,and face J, the toe being hollowed ontin a circular form, with a ledge,K, for holding the pin suspended in making the automatic coupling.

In operating this device the pin L is raised in the draw-head, allowingthe tumbling-latch to fall to the position shown in Figs. 1 and 3 of thedrawings, the pin G being at the upper end of the slot H. The pin isthen lowered and allowed to rest upon the ledge K, ready for thereception of the link M, which may now be inserted in the mouth of thedraw, and, striking the face J, force the tumbling-latch backward andupward the full length of the slot H, thereby drawing the ledge K fromtinder the pin L and allowing it to drop down through the link.

Having thus described myinvcntiomIclailn as new and desire to secure byLetters Patent- An automatic car-coupling consisting of the draw-head A,having within it the latch-block constructed with a flat projecting lipfor the support of the coupling-pin, and an angular slot to move upwardand backward in parallel lines by thepressurc of thc'connecting-link,substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
